Abstract:

The geographical origin traceability of agricultural products, an important part of traceability system, is effective in protecting the quality and safety of agricultural products. Using physical, chemical and biological methods, geographical origin of agricultural products can be analyzed according to specific indexes such as organic constituents, volatile compounds, isotope content and ratio, and DNA mapping. Combined with chemometrics, fingerprint profiles of agricultural products can be established by analyzing component data related to geographical origin of samples. Current analytical techniques used for determining geographical origin of agricultural products are reviewed in this paper. Furthermore, the future development trends are also discussed.

Key words: agricultural product, geographical origin traceability, spectroscopy, mass spectrometry
